Narrow Results

The resonances in H+HLi scattering for nonzero total angular momentum (J > 0) are examined here by a time-dependent wave packet approach employing an ab initio potential energy surface (PES) [Dunne LJ, Murrell JN, Jemmer P, Chem Phys Lett336: 1, 2001] of the system. The resonances are identified by calculating a set of pseudospectra corresponding to the Franck–Condon transition of a hypothetical initial state to the interaction region of the H+HLi PES. The resonances are characterized by calculating their eigenfunctions and linewidth lifetimes. The resonances for J ≠ 0 are discussed in relation to their counterpart for J = 0. The effect of Coriolis coupling on the resonances obtained from the centrifugal sudden approximation for J = 2 and for K = 0,1,2 is examined.

We extend top-on-top model to even-A nuclei, where two particles in different single-particle orbitals (tops) correlate with the triaxial rotor (top). We apply the model to describe the energy levels and transition rates for the triaxial, strongly deformed (TSD) bands in odd-odd nucleus ¹⁶⁴Lu.
